Airport at non-EU country
If you are carrying duty-free merchandise purchased at an EU airport when transferring at an airport outside the EU, you may be prevented from carrying it on board. The rules on liquids, aerosols, and gels there may also differ from those of the EU.
We therefore advise you to get information before flying, for example from an embassy or consulate of the country where you are heading. You’ll find a complete list of foreign embassies and consulates in Germany at www.auswaertiges-amt.de. Please keep in mind that the staff of duty free shops etc. may not be familiar with all current regulations.
